Base adds relevant position to, thus eliminates the activity at end-blocking, and the continuation terminating molecule segment increases.
Preferably, one or both during described auxiliary agent is amino-modified silicone oil and epoxy-modified silicone oil.
Amido silicon oil is the polydimethylsiloxane in side chain or end group containing amino, is introduced by silicon in polyurethane resin,
Improve the resistance to water of polyurethane resin, and there is when making leather more preferable feel, and improve washing speed.
Epoxy radicals silicone oil is the class silicone oil in the side chain of polydimethylsiloxane or end group containing epoxy radicals, can improve
The elasticity of polyurethane resin, strengthens resistance to water, uses the synthetic leather tool that polyurethane resin can be made to make with amido silicon oil allotment
There is more preferable flexibility, improve feel.
The polyurethane resin that the technical program is produced without abscess or fine cell structure, setting rate is moderate, washing is fast
Degree is fast, and anti-hydrolytic performance reaches 12 hours alkaline-resisting rear conservation rates of peeling off more than 80%.
Second goal of the invention of the present invention is to provide the mirror surface leather of a kind of hydrolysis.
